38G solid core? Sure, but you need to work harden it by bending it back and
forth. Also, if someone's iron runs hot, the wire dissolves into the solder
in about 10 secs, so it is easy to thin it below 4 mils without noticing.
38G nickel is much more robust if you're looking for something which stands
up to abuse.

Subject: [TN] Copper wire open

Fellow TechNetters:

   Is it possible for a 4 mil diameter copper wire open without any apparent
signs of elongation, mechanical stress?   Can the copper wire snap cleaning
at the grain boundary?

Victor,
